This is not the whole song but it is right. Use the other tab to find the correct chord 
but this is how you finger pick it

B|--------------3----------------------3--------------3------------------------|
G|----------4-----------------4----4--------------4-------4-----4--------------|
D|------4-----------------4--------------------4-------------4-----------------|
A|--2----------------2----------------------2----------------------------------|
E|-----------------------------------------------------------------------------|

e|-------------------------------------------------------------------------------|
B|-----------3----------------------3--------------------------------------------|
G|-------4------4-----4---------4------4-----4 (play this a few times)-----------|
D|----4------------4---------4------------4--------------------------------------|
A|-2----------------------2------------------------------------------------------|
E|-------------------------------------------------------------------------------|

that is the basic finger picking pattern. Just listen to the song so you will know
when to switch chords
